Step 4 - Prepare the Probe Changer

The calibration process for the FCR25 Probe Changer may vary slightly depending on the types and locations of the inserts for each port. The process described here shows how PC-DMIS manages calibration for each port type.

Once you click the Calibrate button, the following message box appears:

PC-DMIS Message

Each FCR25 unit contains 3 ports. Different types of physical racks can hold varying numbers of FCR25 units. The current rack is configured to have a total of 3 ports, which means it should have 1 FCR25 units.

Please shim open all the lids and remove all modules and styli from the ports.

1. Read the instructions from the preceding prompt, and verify that you have the correct number of ports and FCR25 units (a unit is a set of three ports).

2. Open the lids to each port. Insert the shims, with the large ends of the shims toward the back of the ports to hold them open.

A "shim" is a tapered piece of plastic that fits in between two ports to hold their lids open. The picture below shows a close-up view of a shim between ports 2 and 3, holding their lids open. Without a shim, the lids are shut, as you can see in port 1.

3. With the lids open, remove all of the modules and styli by sliding them forward and out of the ports, as shown below:

4. When you are ready to measure port 1, click OK.

The next step starts the calibration process.
